Failover recovery
1. During recovery plan execution, when SRM reaches the Prepare Storage step, the plan provides
the HP P6000 EVA SRA Software version 5.0 with the DR Group and LUN information needed
for failover. The information includes:
• Recovery site storage array ID
• DR group ID
• Vdisk name
• Recovery ESX server HBA ports (WWNs) for post-failover LUN presentation
2. HP P6000 EVA SRA Software version 5.0 communicates with HP P6000 Command View Software
and fails over each data replication group associated with the LUN information provided by
SRM.
3. HP P6000 EVA SRA Software version 5.0 obtains LUN presentation information for each vdisk
that has failed over and returns the information to SRM. The information includes:
• Vdisk name
• LUN assignment to recovery HBA ports
NOTE:
During initial setup, replicated vdisks must be presented to both the protected and recovery ESX hosts.
If the adapter detects that replication I/O has been suspended, it attempts to resume replication and
wait for resynchronization to complete before attempting failover.
For failover testing, LUN assignment is the LUN used by the snapshot and not the parent vdisk.
Communication path
HP P6000 EVA SRA Software version 5.0 uses the Storage Administration Portal to communicate with
active and passive HP P6000 Command View Software servers in the SAN.
